PACKING AND METHOD OF MAKING SAME.

Application filed February 1, 1922. Serial No. 533,230.

To all. whom it may concern:

Be it known that I, CHARLES C HALL, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and in Packings and Methods of Making Same, of which the following is a specification.

This invention relates to improvements in packings and method of making the same. The main objects of the invention are:

First, to provide an improved packing which is well adapted 'for use under high temperatures also one which is highly efficient, is self lubricating and very durable. Second, to provide an improved method of manufacturing packings having the above recited advantages by means of which the material may be economically produced.

Further objects, and objects relating to structural details. will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

he means and methods followed by me for carrying out my invention are as far as practical illustrated in the accompanying drawing, forming a part of this application, in which Fig. I is a plan view of a sheet of metal.

Fig. H is a plan of the sheet coated with a lubricant paste.

Fig. III is a plan view of the coated sheet of Fig. 11. crumpled.

Fig. IV is a plan and end view of the crinkled sheet with a preliminary fold.

Fig. .V illustrates the crumpled sheet formed into a roll.

Fig. V1 is an end view of the roll of Fig. V.

Referring to the drawing. 1 illustrates a sheet of metal which is of aluminum or aluminum alloy containing at least sixty percent of aluminum. These sheets are preferably about one one-thousandth (1/1000)'of an inch in thicknes and are annealed after rolling. The sheet is then coated with a lubricant paste consisting of high fire test oil and powdered graphite. The coated sheet is then crumpled, as shown in Fig. H, which produces a very irregular surface and is then folded as seen in Fig. IV and then rolled upon itself as seen in Figs. V and VI and thereafter compacted or compressed into the desired form for use or for packaging and transportation, it being formed into a ring or other form, as may be desired.

My improved packing may be handled and used as an ordinary packing as by bending around a shaft or compressing into a tuffing box by means of a gland or forced into place by a tamping or ramming tool.

In the accompanying drawing, I have only attempted to illustrate the steps of manufacture, and it will be understood that the completed packing may be pressed or compacted into any desired form for sale or may be left in the form of the roll or loosely folded, as may be desired.

My improved packing is especially designed for use under high temperatures whichit is capable of withstanding for a long period of time without its efficiency being materially afiected.

Having thus described my invention, what I claim as new and desire'to secure by LettersPatent, is:

1. A packing material consisting of a sheet of aluminum approximating 1/1000 inch in thickness, annealed and crumpled. and coated with a high fire test lubricant oil and graphite, and folded and rolled and compacted together.

2. A packing material consisting of a sheet of aluminum alloy approximating 1/1000 inch in thickness and containing at least 60% aluminum, annealed and crinkled and crumpled, and coated with high fire test lubricant oil and graphite, and folded and compacted together.

3. A. packing material consisting of a sheet of aluminum approximating 1/1000 inch in thickness annealed and crumpled, and coated with a high fire test lubricant oil and graphite, and compacted together.

4:. A packing material consisting of a. sheet of aluminum alloy approximating 1/1000 inch in thickness and containing at least 60% aluminum, annealed and crinkled and crumpled, and coated with high fire test lubricant oil and graphite, and compacted together.

5. A packing material consisting of asheet of aluminum annealed and crumpled, and coated with a paste of high fire test lubricant oil and graphite, and compacted together.

6. A packing material consisting of a sheet of aluminum alloy annealed and crumlubricant, and compacted together.

8. A packing material consisting of a sheet of aluminum alloy annealed and crumpled, and coated with oil'and powdered or flaked lubricant, and compacted together.

a 9. A packing material consisting of a sheet of aluminum, annealed and crumpled and coated with lubricant, and folded together.

10. A packing material consisting of a sheet of aluminum alloy, annealed and crumpled and crinkle-d and coated with lubricant, and 'folded together.

11. The process of producing a packing for use under high temperatures'consisting of forming aluminum into thin sheets of approximately 1/1000 inch in thickness, annealing, coating with a. high fire test lubricant oi1 and graphite and crumpling and compactlng.

12. The process of producing a packing for use under high temperatures consisting of forming an aluminum sheet, annealing the sheet, coating with a paste lubricant, crumpling and compacting 13. The process of producing a packing for use under high temperatures consisting of forming an aluminum alloy sheet, annealing the sheet, coating with a paste lubricant, crumpling and compacting.

In witness whereof, I have hereunto set my hand and seal.
